I moved back in to my college apartment with some crappy ISP. Last spring, I had no problems, but now, my Macbook can connect to the network just fine when booted into Windows, but can't in OS X.
In Windows, it gets a 10.1.x.x IP, in OS X, just a 192.168.x.x address. The same goes for the default gateway- in Windows, 10.1.x.x, in OS X, 192.168.x.x. So it seems like OS X is not detecting network configuration correctly or something. Is there some way I can give it hints but still let the network assign me an IP address? Or any other ideas?
I've had to call the ISP's support multiple times in the past and it is always an excruciating experience so I'm hoping I can fix this myself.
